I went to use my Dreamcast race controller the other day and I found it had developed a fault where the controller was sending a signal of turning right even when the wheel is in its centre position. I was able to see it using the wheel calibration in Sega Rally where it was pulling almost 50% right input. Turning it further right would increase it to 100% and turning the wheel fully left, I could only achieve about 50% left turn input. I unplugged the wheel and restarted the Dreamcast but it still remained.

Does anyone know what the issue is and if it can be fixed?

Following a video on YouTube, I've opened up the controller and had a look inside. It was really clean, very little dust and nothing stood out as being at fault. I re-greased the steering column and sprayed some contact cleaner into the potentiometer.

Unfortunately after putting it back together the issue remained, although rather than pulling 50% right it's around 29% now. It's possible something on the PCB or the potentiometer is at fault but I am unable to go any further as I don't have electrical engineering knowledge.
